[QUOTE="1mechanic, post: 2187343, member: 116213"] Sometimes I have a hard time expressing my thoughts into words but after reading the article posted by JustMe2 it confirms something I considered on boat tail bullets. As you reduce the area in front of pressure, the pressure increases like putting your thumb over the end of a hose. With the taper of the boat tail as the burning gun powder pushes against the base the gasses going up the sides will increase in pressure blowing past the bearing surfaces of the bullet to bore, like blow by on cylinder rings, producing more gasses in front of the bullet to effect trajectory. The problem I have is I like the B.C. on the boat tails and want to shoot them over the flat base but want the flat base accuracy. lol [/QUOTE]
